Could Your Medication Be Causing Angioedema?
Published: Feb 19, 2024
Angioedema can be a scary side effect of certain medications. Let's dive into what causes it and how to recognize the symptoms.
Understanding Angioedema
Angioedema is a swelling of the deeper layers of the skin, often affecting the face, lips, and sometimes the throat, which can be life-threatening if it blocks the airway. It is often accompanied by hives and is usually caused by drug allergies. Common triggers include antibiotics, NSAIDs, and ACE inhibitors.
Timing and Triggers
Angioedema can occur at any time during drug treatment, although it's more common in the first few weeks. ACE inhibitors are notorious for causing this reaction, sometimes months after starting the medication. Non-IgE-mediated mechanisms are often involved, leading to swelling without any other allergic symptoms.
Quick Action is Key
If angioedema affects the airway, it's a medical emergency. Treatment often involves stopping the offending drug and administering antihistamines or corticosteroids. In severe cases, epinephrine may be required to reduce swelling quickly and restore normal breathing.
